This document provides a sample configuration for tunneling an IPv6 Routing Information Protocol (RIP), and an IPv6 Border Gateway Protocol (BGP) network and traffic through a pre-existing IPv4 network. This technique allows you to connect IPv6 sites over the IPv4 backbone that exists.
A correlation by itself is often not very informative. A large correlation does not necessarily indicate causality. If one or both of the variables involved in the correlation are related to some third variable, the correlation may change substantially when controlling for that third variable. In this case, the SAT I (aptitude) score is highly correlated with high school GPA and with subject achievement test scores on the SAT II.
What is the correlation coefficient. The correlation coefficient, or Pearson product-moment correlation coefficient (PMCC) is a numerical value between -1 and 1 that expresses the strength of the linear relationship between two variables.When r is closer to 1 it indicates a strong positive relationship. A value of 0 indicates that there is no relationship. Values close to -1 signal a strong negative relationship between the two variables. You may use the linear regression calculator to visualize this relationship on a graph. Correlation coefficient formula. There are many formulas to calculate the correlation coefficient (all yielding the same result). This calculator uses the following:
